TECHNICAL FIELD

The present disclosure generally relates to a skin cleansing device, and more particularly to a hand-held device with an interchangeable head for selectively targeting skin areas for cleansing.

BACKGROUND

Proper skin care is important for heath and cosmetic reasons. Skin is a vital organ and a breakdown in the skin can adversely affect the skin's function as a barrier and make it susceptible to infection. A breakdown in the skin can also be very painful, such as the case of excessive dry skin. Visual irregularities in the skin can adversely affect a person's confidence and other people's perceptions.

Various cleansing devices and products have been developed that target removal of unwanted materials from the skin, such as through pore cleansing. Some devices utilize vacuum suction to draw material out of pores. However, such devices are often only available in a medical professional setting and may be uncomfortable and unsuitable for personal use. Further, the devices that have been developed for personal at-home use do not provide versatility that may be needed to address different skin areas and/or to provide a variety of skin cleansing options.

The present disclosure is directed to providing an improved skin cleansing device that overcomes at least some of the problems of current skin cleansing devices.

DETAILED DESCRIPTION

The present disclosure describes embodiments of a skin cleansing device. The skin cleansing device includes a base body sized for hand-held use and one or more cleansing heads which are removably connectable to the base body. The base body houses internal components which are configured to generate suction that is translated through the attached cleansing head. For example, the base body may include a vacuum pump that creates suction in a vacuum line fluidly connected to the cleansing head. The vacuum pump thereby generates a suction force at an inlet of the cleansing head. A user may apply the cleansing head to a targeted skin area in order to utilize the suction force to draw material out and/or off of the skin, such as to cleanse and unclog pores, remove blackheads, and the like.

In at least some embodiments, the base body is configured for interchangeable connection with a plurality of different cleansing heads to provide a degree of versatility to the device. For example, a first cleansing head may include a broader, larger inlet that allows for general skin cleansing of a relatively large area fairly quickly. A second cleansing head may include a smaller inlet that may be used to target specific spots or areas of skin, such as the location of a blackhead or clogged pore. Other cleansing heads may be provided and may include alternative and/or additional features configured to perform cleansing tasks during use. The combined base body and plurality of interchangeable heads may be provided as part of a cleansing kit.

In some embodiments, at least one interchangeable cleansing head may include relatively-movable components that enhance the functionality of the device, such as to improve comfort and use of the device. For example, a cleansing head may be configured with an outer housing that is slidable with respect to an inner nozzle such that the inner nozzle is retracted into the outer housing prior to use. The outer housing may be formed as a tubular shell and the inner nozzle formed as an inlet nozzle for containing the fluid flow produced by the vacuum pump. The inlet nozzle may be directed to a specific spot on the user's skin by the outer housing being placed at the spot and applying a force to slide the outer housing, moving the inlet nozzle inward until it contacts the skin.

In some embodiments, a cleansing composition may be provided and used in combination with the cleansing device to enhance the cleansing functionality. The cleansing composition may be selected from a group of skin care agents that prepare the skin for a cleansing process using a disclosed cleansing device. For example, the composition may prepare pores for a blackhead removal process using a blackhead removal head as part of the cleansing device. The preparation may include softening the skin, enlarging the pores, or otherwise treating the skin prior to applying the suction force provided by the skin cleansing device. One or more cleansing compositions in the form of a skin care agent may be provided with the skin cleansing device as part of a kit.

FIG. 1 is a perspective view of an exemplary embodiment of a skin cleansing device 10 being held by a user. The skin cleansing device 10 includes a base body 12 and a cleansing head 14A. The base body 12 is preferably configured to be held in a user's hand and may include an elongated shape leading up to the cleansing head 14A. The cleansing head 14A is preferably removably connectable to the upper portion of the base body 12 such that a plurality of cleansing heads may be interchangeably selected and connected to the base body 12. The user may move the skin cleansing device 10 such that the cleansing head 14A is against or adjacent to a targeted area of skin and the base body 12 (via internal components) may produce a suction force at an inlet 16A of the cleansing head 14A, to thereby draw materials out and off of the skin. For example, the suction force may draw a portion of skin itself into the inlet 16A with the materials (e.g., dirt, debris, blackheads, cleansers, makeup, cosmetics, etc.) being drawn into a cavity of the cleansing head 14A. Each cleansing head 14A may be a self-enclosed element that may be selectively connected to the base body to transfer, concentrate, and/or target a suction force generated by the skin cleansing device 10.

FIGS. 2A-2D further illustrate an exemplary embodiment of the base body 12. The base body 12 may include an outer surface 18 for being gripped and held by a user. The base body 12 may include an ergonomic shape that promotes ease of use with regard to placing a connected cleansing 14A head at a desired location on the skin. For example, the base body 12 may include an enlarged lower portion 20 that creates a larger base for holding by the user and a narrowed upper portion 22 that extends from the lower portion 20 and connects to the cleansing head 14A. The lower portion 20 may include a curved or rounded shape while the upper portion 22 is formed as a square or rectangular neck, although embodiments are not limited to this configuration. A primary axis P1 upper portion 22 may extend at an angle or slope backward slightly such that the cleansing head 14A presents at an angle with respect to a primary axis P2 of the lower portion 20 of the base body 12. This configuration may allow for more comfortable gripping of the base body 12 and placement of the cleansing head 14A during use of the skin cleansing device 10. Moreover, the cleansing head 14A may be configured such that a primary axis P3 the cleansing head 14A is perpendicular to the primary axis P1 of the neck of the upper portion 22. For example, the primary axis P3 around which the inlet 16A is formed may extend at an approximate 90 degree angle with respect to the primary axis P1 of the neck of the upper portion 22 of the base body 12. This configuration may provide an effective viewing angle for the user to view placement of the cleansing head 14A on their own skin. However, it should be understood that embodiments are not limited to the relative positioning of the components as illustrated.

The base body 12 may include the outer surface 18 being formed as part of an outer shell that encloses internal components that generate the suction force for the skin cleansing device 10. The internal components may, in some embodiments, be controlled by at least one control button 23 that is accessible on or around the outer shell of the base body 12. In some embodiments, the control button 23 may be positioned at a downward-facing bottom surface of the base body 12. The outer shell of the base body 12 may include other features, such as an exhaust opening/vent. The base body 12 may be formed as a single component or may be made up of more than one connected components.

The base body 12 may further include a mount 24 for the connecting to a selected cleansing head 14A. The mount 24 may be positioned at a top of the upper portion 22. The mount 24 may include an opening 26 (shown in FIG. 3 ) that leads into an interior of the base body 12. The mount 24 may further include a support surface 28 for supporting and contacting a portion of the cleansing head 14A. The support surface 28 may be shaped and configured to mate with a corresponding shape of the cleansing head 14A. In an exemplary embodiment, the support surface 28 includes a rounded, concave shape to receive a corresponding rounded shape of the cleansing head 14A. The mount 24 may include one or more sealing elements, such as a gasket, O-ring, or the like to create a seal when connected to the cleansing head 14A. The mount 24 allows the base body 12 to be connected to one of a variety of cleansing heads that may be at least partially inserted into the opening 26 in order to create a fluidic connection to allows a suction force originating in the base body 12 to be translated to the inlet 16A of the cleansing head 14A.

FIG. 3 is a cross-sectional view of the base body 12, taken along line A-A of FIG. 2A. The base body 12 preferably includes one or more internal cavities for housing internal components. The internal components include, for example, a vacuum pump 30, a power source (e.g., a battery) 32, a printed circuit board 34, a vacuum line 36, and an exhaust line 38. The base body 12 may also include one or more connecting channels that support fluid flow, such as a channel 40 to connect the vacuum line 36 to the opening 26 and a channel 42 to connect the exhaust line 38 to a vent 44. The term “channel” as used herein refers generally to a passageway configured to direct a flow of fluid (e.g., air) from place to another (e.g., one end of the channel to an opposite end of the channel) and it is not limited to being formed in any particular manner.

The vacuum pump 30 may be any of a number of devices configured to generate a suction force by pulling air into the vacuum pump 30 through the vacuum line 36 and expelling the air through the exhaust line 38. The vacuum pump 30 is preferably powered by the battery 32, which is also housed in the base body 12. The battery 32 may be, for example, a rechargeable battery. In another embodiment (not shown) a power cord could be used to power the device. The printed circuit board 34 may be a control element configured to send signals to and from the vacuum pump 30, such as to turn the vacuum pump 30 on and/or off. For example, the printed circuit board 34 may include electronic control elements that react to a pressing of the control button 23 by generating and sending an on/off signal to the vacuum pump 30 to selectively control operation of the vacuum pump 30. In operation, when the vacuum pump 30 is on, fluid flow is drawn down from the opening 26, through the channel 40, through the vacuum line 36, into the vacuum pump 30, and a corresponding fluid flow is created out of the vacuum pump 30, through the exhaust line 38, through the channel 42, and out of the vent 44.

FIGS. 4A-4E further illustrate an exemplary embodiment of the cleansing head 14A, which may be considered a first cleansing head 14A. The first cleansing head 14A may be a cleansing head configured for generic skin cleaning by creating a suction force at a broad inlet 16A. The first cleansing head 14A may be dragged across the user's skin to collect unwanted material (e.g., dirt, debris, cleanser, makeup, cosmetics, etc.) that may present. In an exemplary embodiment, the first cleansing head 14A may include a collection portion 46 and a mounting portion 48.

The collection portion 46 may be formed as a container for transferring fluid flow into the mounting portion 48 and receiving skin and/or material from the skin targeted by the first cleansing head 14A. For example, the collection portion 46 may include an internal cavity 50. The collection portion 46 may form the inlet 16A which is configured for contacting the skin. The collection portion 46 may include a contact surface 52 that surrounds the inlet 16A. The contact surface 52 may be angled or curved in a manner that gradually approaches the inlet 16A. In some embodiments, the inlet 16A may be optionally surrounded by a ring of soft contact material (e.g., rubber, silicone, etc.). The collection portion 46 may be formed a rounded head an include a shape that compliments the concave shape of the support surface 28. For example, the collection portion 46 may have a convex shape at a lower portion 20 thereof.

The mounting portion 48 is configured to connect to the mount 24 of the base body 12. The mounting portion 48 may include, for example, a stem 54 extending away from the collection portion 46. The stem 54 may create a channel 56 for directing the fluid flow from the inlet 16A to the opening 26 of the mount 24. The stem 54 may be connected to the collection portion 46 by an intermediate portion 57. The intermediate portion 57 may include a shape that matches a shape of the opening 26 such that the intermediate portion 57 mates with the mount 24 when connected. For example, in one embodiment, the intermediate portion 57 includes a triangular shape. As shown in FIG. 4A, the intermediate portion 57 may include a curved, concave surface that matches a curved, convex portion of the support surface 28. The stem 54 may include an O-ring 58 or other sealing element configured to engage in the opening 26 in the mount 24 and help retain the first cleansing head 14A to the base body 12 and create a tight seal. The stem 54 may further include one or more protrusions 59. The one or more protrusions 59 may be used to further secure the stem 54 in place in the mount 24 of the base body 12. The one or more protrusions 59 may be separated from each other, or may be embodied as a protrusion extending around a circumference of the stem 54.

FIG. 5A is a cross-sectional view of the first cleansing head 14A, taken along line B-B of FIG. 4C. This view further illustrates the internal cavity 50 within the collection portion 46. The collection portion 46 may include a back panel 60 that may be removable for ease of cleaning of the first cleansing head 14A. This view also further illustrates the channel 56 of the mounting portion 48 that extends through the stem 54. As shown, the first cleansing head 14A may also include a filter element 62 positioned between the internal cavity 50 and the channel 56. The filter element 62 allows air to flow through but blocks materials that are pulled through the inlet 16A from entering the channel 56. In some embodiments, the filter element 62 may be a valve, such as a one-way valve. In certain embodiments, the first cleansing head 14A is disposable. The first cleansing head 14A collects the unwanted material (e.g., dirt, debris, cleanser, makeup, cosmetics, etc.) in the collection portion 46 preventing the contamination of the base body 12 and its internal components, accordingly additional cleaning or sanitizing of the base body 12 is not required.

FIG. 5B is a cross-sectional view of the cleansing head 14A connected to the base body 12 through the mount 24, taken as a zoomed-in view at the dotted circle of FIG. 3 . The stem 54 is inserted into the opening 26 of the mount 24, thereby fluidly connecting the channel 40 with the channel 56. In some embodiments, the stem 54 may generally converge toward the bottom end and generally match a converging shape of the channel 40 in order to allow the stem 54 to easily move within the channel 40 until an interference point is reached. The O-ring 58 may eventually contact the side of the channel 40, thereby restricting movement of the stem 54. The mount 24 may further include a spring clip 63 or other biasing element configured to mate with the one or more protrusions 59 to further retain the cleansing head 14A in the mount 24. The spring clip 63 may be biased inside of the channel 40 but retract as a result of contact with the protrusions 59 as they move further into the channel 40. The spring clip 63 may return to its biased position after the protrusions 59 pass in the channel 40, thereby locking the stem 54 in the channel 40. The connection may be secure but may be removable upon a pulling force. In other embodiments, a spring clip release button may be included.

The support surface 28 includes an inner portion inside of the opening 26 that mates with and/or supports the intermediate portion 57. The collection portion 46 may rest on an outermost part of the support surface 28. Accordingly, the shape of the stem 54, the shape of the channel 40, the O-ring 58, the protrusions 59, the spring clip 63, the support surface 28, the intermediate portion 57, and the collection portion 46 may each contribute to the connection between the cleansing head 14A and the mount 24 of the base body 12, thereby creating a sealed, removable connection that enables a fluid flow from the vacuum pump 30 to the internal cavity 50. However, it should be understood that embodiments are not limited to including each of these connection features, and that alternative embodiments may include one or more of these features to create the connection between the cleansing head 14A and the mount 24. For example, the stem 54 may include one or more indented portions that mate with a second O-ring inside of the channel 40.

FIGS. 6A-6E further illustrate an exemplary embodiment of a second cleansing head 14B. The second cleansing head 14B may be formed as a targeted pore cleansing head that includes an inlet 16B that is smaller than the inlet 16A of the first cleansing head 14A. The second cleansing head 14B, may be, for example, a blackhead cleansing head configured for specific targeting of a blackhead or other type of clogged pore or dirty pore that can be cleaned through the suction force generated by the skin cleansing device 10. The second cleansing head 14B may include similar features to those described above with respect to the first cleansing head 14A, as will be described below. For example, the second cleansing head 14B may also include a collection portion 64 and a mounting portion 66. The second cleansing head 14B may be interchangeably connected to the base body 12 in a same or similar manner as the first cleansing head 14A and features and functions described with respect to the first cleansing head 14A may apply equally to the second cleansing head 14B in at least some embodiments. In certain embodiments, the second cleansing head 14B is disposable. The second cleansing head 14B collects the unwanted material (e.g., dirt, debris, cleanser, blackhead, sebum, etc.) in the collection portion 64 preventing the contamination of the base body 12 and its internal components, accordingly additional cleaning or sanitizing of the base body 12 is not required.

The collection portion 64 may include an internal cavity 68 connected to the inlet 16A. The internal cavity 68 may be formed as a narrow tube. The collection portion 64 may further include an outer housing 70 and an inner nozzle 72. The outer housing 70 may be relatively-movable (e.g., slidable) with respect to the inner nozzle 72. The inner nozzle 72 may form the internal cavity 68 and the inlet 16B. The outer housing 70 may form a shell around the inner nozzle 72 within which the inner nozzle 72 may move. The outer housing 70 may be formed as a rounded, tubular structure with an aperture 74 that is adjacent to and surrounds the inlet 16A. The shape of the outer housing 70 may mate with the shape of the mount 24 of the base body 12 (e.g., the convex shape of a lower portion of the outer housing 70 may match the concave portion of the support surface 28).

The mounting portion 66 is configured to connect to the mount 24 of the base body 12. The mounting portion 66 may include, for example, a stem 76 extending away from the collection portion 64. The stem 76 may create a channel 78 for directing the fluid flow from the inlet 16B to the opening 26 of the mount 24. The stem 76 may be connected to the collection portion 64 by an intermediate portion 80. The intermediate portion 80 may include a shape that matches a shape of the opening 26 such that the intermediate portion 80 mates with the mount 24 when connected. For example, in one embodiment, the intermediate portion 80 includes a triangular shape. As shown in FIG. 6A, the intermediate portion 80 may include a curved, concave surface that matches a curved, convex portion of the support surface 28. The stem 76 may include an O-ring 82 or other sealing element configured to engage in the opening 26 in the mount 24 and help retain the second cleansing head 14B to the base body 12 and create a tight seal. The stem 76 may also include protrusions 83 that mate with the spring clip 63 in the channel 40 of the base body 12.

FIG. 7 is a cross-sectional view of the second cleansing head 14B, taken along line C-C of FIG. 6C. This view further illustrates the collection portion 64 and the relative positioning of the inner nozzle 72 inside of the outer housing 70. FIG. 7 further illustrates biasing element 84 that influences the position of the inner nozzle 72 relative to the outer housing 70. For example, the biasing element 84 applies a force to the inner nozzle 72 that maintains the inner nozzle 72 in a retracted position in which the inlet 16A is present in the cavity 68. In an exemplary embodiment, the outer housing 70 includes a bearing surface 86 that contacts a first end of the biasing element 84 and the inner nozzle 72 includes a bearing surface 88 that contacts a second end of the biasing element 84.

The outer housing 70 further includes a slot 90 that receives the stem 76. The slot 90 extends in a direction parallel to a longitudinal direction of the second cleansing head 14B to enable movement of the inner nozzle 72 with respect to the outer housing 70. For example, the slot 90 allows the outer housing 70 to move such that the aperture 74 moves toward the inlet 16A until the inlet 16B is outside of or at least flush with the aperture 74 of the outer housing 70. The movement of the outer housing 70 moves the bearing surface 86 toward the bearing surface 88, compressing the biasing element 84, and exposing the inlet 16B.

FIG. 7 further illustrates that the channel 78 connects to the cavity 68 through an optional filter element 92. In some embodiments, the optional filter element 92 may be a valve, such as a one-way valve. An optional removable back panel 94 may provide access to the filter element 92 and cavity 68 for ease of cleaning. In use, a fluid flow is created from the inlet 16B, through the cavity 68, filter element 92, and channel 78 and into the opening 26 of the base body 12. The vacuum pump 30 generates the fluid flow and the seal between the stem 76 and mount 24 focuses the suction force at the inlet 16B. The outer housing 70 is biased to keep the inlet 16B retracted until a force is applied to move back the outer housing 70 and expose the inlet 16B. This force may be generated, for example, through a user pressing the tip of the outer housing 70 against their skin. This gradual exposure of the inlet 16B to the user's skin helps lead to more comfortable use of the targeted suction force.

FIG. 8A is a side view of the second cleansing head 14B in a first position and FIG. 8B is a side view of the second cleansing head 14B in a second position. In the first position, the second cleansing head 14B includes the inner nozzle 72 retracted into the outer housing 70 through the force of the biasing element 84. In the second position, the outer housing 70 has been moved relative to the inner nozzle 72 such that the inlet 16B is exposed.

FIGS. 9A-9D further illustrate the second cleansing head 14B being connected to the base body 12. As shown, the second cleansing head 14B may be connected to the base body 12 in the same or similar manner as the first cleansing head 14A such that the second cleansing head 14B may be positioned for use. The second cleansing head 14B may extend outwardly from the mount 24. A user may position the inlet 16B adjacent to a target area of the skin for use.

FIGS. 10A-10B illustrate an exemplary embodiment of a third cleansing head 14C. The third cleansing head 14C may be formed as a dermaplaning cleansing head that includes an inlet 16C having one or more air channels 96 that are formed inside of an elongated perimeter wall 98 of the cleansing head 14C. In an exemplary embodiment, the air channels 96 are formed at the sides of one or more dermaplaning blades 100. In some embodiments, one or more abrasive material surfaces 102 are positioned on top of, overlapping with, and/or adjacent to the blades 100.

The third cleansing head 14C may include similar features to those described above with respect to the first cleansing head 14A and/or second cleansing head 14B. For example, the third cleansing head 14C may also include a collection portion 104 and a mounting portion 106. The third cleansing head 14C may be interchangeably connected to the base body 12 in a same or similar manner as the first cleansing head 14A and features and functions described with respect to the first cleansing head 14A may apply equally to the third cleansing head 14C in at least some embodiments. For example, the collection portion 104 may include an internal cavity 108 connected to the inlet 16C for collecting debris. Further, the mounting portion 106 is configured to connect to the mount 24 of the base body 12 via a stem 110 extending away from the collection portion 104. The stem 110 may also include protrusions 112 that mate with the spring clip 63 in the channel 40 of the base body 12. In certain embodiments, the third cleansing head 14C is disposable.

The third cleansing head 14C assists in removing and collects unwanted material (e.g., dirt, debris, cleanser, blackhead, sebum, etc.) in the collection portion 104, thereby preventing the contamination of the base body 12 and its internal components. The blades 100 and abrasive surfaces 102 may assist in removing hair and exfoliation as the third cleansing head 14C passes across the user's skin. The air channels 96 create suction of the skin at the blades 100 and abrasive surfaces 102 and may help to hold the skin at an appropriate angle for dermaplaning and/or exfoliation. The third cleansing head 14C thus provides an additional skin care option for a user of the skin cleansing device 10.

FIGS. 11A-11B illustrate an exemplary embodiment of a fourth cleansing head 14D. The fourth cleansing head 14D may be formed as an abrasive cleansing head that includes an inlet 16D surrounded by an abrasive surface 114. In an exemplary embodiment, abrasive surface 114 includes a plurality of adjacent abrasive sections 116, each with a different level of abrasiveness (e.g., varying degrees of grit, protrusion patterns, abrasive materials, hardness levels, etc.). In an exemplary embodiment, the abrasive surface 114 includes a selected abrasion pattern of the plurality of abrasive sections 116 to enhance skin cleansing and removal of debris and unwanted material from the skin according to a target of each abrasive section 116 (e.g., varying sizes of debris). In an exemplary embodiment, the fourth cleansing head 14D is formed from a plastic (e.g., via molding, laser etching, etc.) and the abrasion pattern is tooled directly into the plastic, thereby not requiring separate attachment of an abrasive material to the head. In some embodiments, the abrasive surface 114 includes a concave configuration leading to the inlet 16D at a center, the inlet 16D of the skin.

The fourth cleansing head 14D may include similar features to those described above with respect to the first cleansing head 14A, second cleansing head 14B, and/or third cleansing head 14C. For example, the fourth cleansing head 14D may also include a collection portion 118 and a mounting portion 120. The fourth cleansing head 14D may be interchangeably connected to the base body 12 in a same or similar manner as the first cleansing head 14A and features and functions described with respect to the first cleansing head 14A may apply equally to the fourth cleansing head 14D in at least some embodiments. For example, the collection portion 118 may include an internal cavity 122 connected to the inlet 16D for collecting debris. Further, the mounting portion 120 is configured to connect to the mount 24 of the base body 12 via a stem 124 extending away from the collection portion 118. The stem 124 may also include protrusions 126 that mate with the spring clip 63 in the channel 40 of the base body 12. In certain embodiments, the fourth cleansing head 14D is disposable.

The disclosed embodiments describe a skin cleansing device that includes interchangeable and removable self-enclosed cleansing heads that are connectable to a base body. The skin cleansing device is formed as a hand-held device for personal use and has features and components that create promote ergonomic and comfortable use during a skin cleansing process. The interchangeability of the cleansing heads provides a versatility to the skin cleansing device, thereby enabling differing types of cleaning. The cleansing heads include a blackhead removal cleansing head with movable components for enabling a smooth approach of an inlet toward the user's skin. The skin cleansing device includes aesthetic, ornamental and functional aspects. The skin cleansing device configuration and geometry may have different shapes, arrangements, textures, etc. while achieving the same or equivalent functionality.

Some embodiments of the disclosed system may include a product or kit that includes a base body as a reusable component and a plurality of disposable heads that can be used a limited number of times. This embodiment encourages clean and sanitary use while providing versatility across different types of cleansing heads and enabling multiple users to share the same base body while maintaining use of separate cleansing heads. The disclosed embodiments are applicable to a method of use that includes selecting a cleansing head, installing the cleansing head on the base body, using the device to remove dirt, debris, cosmetic product, etc. from the user's skin, and removing the cleansing head for ease of cleaning and reuse of the base body with the same or a different cleansing head. The removability of the cleansing heads enables easier disposal of the material removed from the skin and helps to provide a long life-cycle of the base body by inhibiting build-up of material and/or clogging of the functional components of the vacuum source. In particular, a composition present on the skin, such as makeup or other topical agents, may be kept separate from the base body such that clogging and build-up is inhibited. Moreover, the disposable cleansing head has a filter and/or sealing element (e.g., gasket, O-ring) such that these elements are changed together with the cleansing head, avoiding build-up and deterioration around these parts. As a result of these combined features, continued use of the base body with an accompanying composition providing a synergistic effect is possible.
